Nice piece.
I agree with changing it up a bit....the same repeating lick.... vary it a bit..... add the octave up, vary the lick a bit as it moves through the song. Lengthen the notes to give a more spacy feeling.....add verb to it as well.....
I didn't get a feeling from the music that I was among the stars floating...mostly from the short duration of the notes in the lick with no verby feel...... not like I was expecting based on the title.
A little more work by editing some things and I think that basic underlying song works fine.
Yeah.... move something to the top and it will get more plays..... people only go 2 or 3 songs down in most play lists on the net. Impatient people.... needing instant gratification or they are out and looking it somewhere else....
